  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • WebRTC Multi-Stream recording

    11 janvier 2021, par Tim Specht

    I'm currently trying to build a WebRTC streaming architecture that contains multiple users streaming content from their camera in the same "room" and a SFU / MCU on server-side "recording" the incoming video packets, merging them into one image and re-distributing them to the viewers as either RTMP or HLS for added scalability.

    


    Upon doing some initial research on this, Janus Gateway seems like a good fit for this given it's wide adoption across the space + their (seemingly) extensible plugin architecture. Thus, I'm currently trying to figure out what a recommended architecture for my use-case would look like.
I looked at the following plugins :

    


    


    While Janus and the Streaming plugin seem like a good start to get the broadcasting aspect within the group of casters in the room, I'm trying to piece together how I could combine the different video sources into a combined one (split horizontally for example if there are 2 casters active) and retransmit the final result as something optimized for broadcast-consumption like HLS. Some of the ways I could imagine doing that :

    


      

    • Implement a custom Janus plugin that transcodes the incoming buffers on the gateway itself

      • 


    • Forwarding the incoming packets via RTP to a Transcoding server

        

      • In this specific case I am not sure what would be best to implement that ? Are the video frames different tracks ? Could I stream all of them to the same port and have ffmpeg or something similar take care of the merging for me ?

  • How to use yadif filter in ffmpeg ?

    2 juin 2015, par Pavel

    I write application on C++ with ffmpeg. I read interlaced frames with opencv VideoCapture and convert it to AVFrame for use yadif filter.
    Can you give me simple example with yadif filter using ? filtering_video.c from ffmpeg docs is too broad

  • Ubuntu ffmpeg command -i not found

    12 avril 2016, par Gerwin

    I’m a beginner with Ubuntu and I need to setup a streaming server for my company, I’ve installed NGINX and FFMPEG, but when I call ffmpeg -i in the ~/ffmpeg/ffmpeg directory it returns an error command not found but when I call ./ffmpeg -i it returns a list with configurations.. why does ffmpeg -i not work and how can I fix it ?

    I think that the Path Enviroment Variable is incorrect but how would I go abouts changing said variable ? I’m not that experienced with Ubuntu / CMD programming / FFMPEG configuration.
